The pin - tuck sports bands are very secure. I have used the original apple watch since it came out and have only used the sport band that came with it. I have hiked, biked, lifted weights, played with my children, rock climbed, danced....many activities...with out the watch ever coming loose or adjusting. It was very comfortable and the fit was great.
